No instance of overloaded function "std::vector<_Ty, _Alloc>::push_back [with _Ty=Ort::Float16_t, _Alloc=std::allocator<Ort::Float16_t>]" matches the argument list

I am encountering the error in detector.cpp at this line

inputTensorValuesFp16.push_back(float32_to_float16(fp32));

I can see that the declaration of inputTensorValuesFp16 is std::vector<Ort::Float16_t> inputTensorValuesFp16;

Also the function float32_to_float16 returns uint16_t static uint16_t float32_to_float16(float& input_fp32)

Is this some bug? Or am i missing something here?

[jason-li-831202]

inputTensorValuesFp16.push_back(float32_to_float16(fp32)); Typically, this is only used when the model is in fp16. If you use the following parameters during conversion by convertPytorchToONNX.py: --half : Convert fp32 to fp16 model.

could you please provide the full error message?

Hello Jason, Thanks for your feedback. But I encounter this error during build process.
